I have a 1995 subaru legacy with the standard 2.2L 4cyl. The check engine light came on, which turns out to be for code P0141, O2 heater loop fail, Bank 1 Sensor 2.
The first issue is whether this is a problem with the sensor itself or whether there is a problem with, for example, the wiring harness.
The second issue is that this code usually refers to a downflow sensor (i.e. beyond the catalytic converter), but I can't find anyone that sells anything specifically downflow for this model year. Does this mean that both sensors are the same part? Or do I need to get a "universal" sensor and crimp some wires together?
